Chee, who spoke just last week at UBS’s Greater China conference in Shanghai, plans to leave the banking industry and is considering setting up his own investment fund, said one of the people, who asked not to be identified because the information is private.

As head of Asia corporate client solutions, Chee was responsible for overseeing UBS’s regional mergers advisory, capital markets and financing for companies, financial institutions and private-equity firms. He was left as sole head of the business after Saurabh Beniwal’s departure last year.
